Reloading the bpmn2 diagram [message #1087285]

Hi,

Has i mentioned before i'm manipulating the bpmn2 elements colors and other visual elements and i would like to clean it all up when i stop the animation.
Just like if i was opening the bpmn2 file in a diagram at the moment i stop.

Can i do this by code?

Or instead, do i have to call another customFeature that applies the bpmn2 visual preferences to the diagram elements?

Thank you,
Regards
Marco Roque

Hi Marco,

You could use something like the following to reset the default colors and styles for all PictogramElements:

		TreeIterator<EObject> iter = getDiagram().eAllContents();
		while (iter.hasNext()) {
			EObject o = iter.next();
			if (o instanceof PictogramElement) {
				PictogramElement pe = (PictogramElement) o;
				GraphicsAlgorithm ga = pe.getGraphicsAlgorithm();
				EObject bo = Graphiti.getLinkService().getBusinessObjectForLinkedPictogramElement(pe);
				if (ga!=null && bo instanceof BaseElement)
					StyleUtil.applyStyle(ga, (BaseElement)bo);
			}
		}

HTH,
Bob

Hi Bob,

Thank you very much. The code really does what i wanted. I just tweaked it a little bit so the gateways and events don't get a rectangle background.
So the final result was this:

TreeIterator<EObject> iter = editor.getDiagramTypeProvider().getDiagram().eAllContents();
					while (iter.hasNext()) {
						EObject o = iter.next();
						if (o instanceof PictogramElement) {
							PictogramElement pe = (PictogramElement) o;
							EObject bo = Graphiti.getLinkService().getBusinessObjectForLinkedPictogramElement(pe);
							GraphicsAlgorithm ga = null;
							
							//Code for getting the graphicAlgorithms
							if(bo instanceof BaseElement && bo instanceof Gateway){
								ga = PictogramUtils.getPolygonFromPictogram(pe);
							}else if(bo instanceof BaseElement && bo instanceof Event){
								ga = PictogramUtils.getEllipseFromPictogram(pe);
							}else {
								ga = pe.getGraphicsAlgorithm();
							}
						
							if (ga!=null && bo instanceof BaseElement)
								StyleUtil.applyStyle(ga, (BaseElement)bo);
							
						}
					}

Cool, glad I could help Smile

I'd be REALLY interested in seeing what you're working on, as process debugging and tracing is on my list of advanced features after a 1.0 release (coming soon, I hope!) Is this something you could share with the open source community or is it proprietary?

Thanks,
Bob
